To all v'whom 'it may concern.

Be it known that I, JOHN R. MACK, a citizen of the United States, residing at New York, in the county of New York and State of 4New York, have invented certain new andl useful Improvements in Carbureters, of which the vfollowing is a specification, reference being had therein to the casing divided into a lower invertedly tapered chamber and anA upper chamber, the lower chamber being provided with a centrally arranged air inlet while the up er chamber is provided with a carburete air outlet, whlch is vertically above the air inlet and is connected to the manifold of the engine. The communication between these chambers is controlled by a flat sliding valve, which regulates the admission of air into and through the, large upper chamber, in which directly above and parallel with, of slightly reater width than the air admission slot, 1s the loil feed pipe, in which is slidingly mounted a piston or cylindrical valve, which is operated simultaneously with the flat sliding valve, both being connected together exteriorly of the casing. The piston valve is slightly lshorter than the flat valve, so

that the first of a series of nozzles mounted upon the upper side of the o il feed pipe, is Opened to allow the priming oil to be sprayed or atomized in three directions, namely upward and centrally of the nozzle and to opposite sides of the feed pipe; and after the engine has been started, the valves are moved so as to open the air admission slot and as many of the nozzles, as may be desired. The air in being drawn upwardly passes u on both sides of the feed pipe, and as the oi is sprayed or atomized under pressure, the heavier the oil the greater' the pressure, and in the direction above stated, the air is thoroughly carbureted, within a removably tapered dome or casing, whose upper tapered endconducts the broken streams of carbureted air toward each other, causing a greater commingling of the same before the carbureted air passes to the en- -paralleling the slot 9, are the two gine. I have found by experiments and tests, that this form of carbureter, will produce a carbureted air from any class of oil, heavy, medium or light, and that when the valves are properly adjusted that there will be complete combustion of the carbureted air, demonstrating beyond a doubt, that the full efficiency of carbureted air and the engine is being obtained.

To clearly illustrate my invention, attention is invited to the accompanying drawings, in which-- Figure l is a side elevation of the complete carbureter in operative position. Fig. 2 is a vertical central sectional view of the same, and Fig. 3 is a detail section of one of the nozzle tips removed and enlarged. Fig.

4 is a side elevation of the carbureter, oil

l6 is a cross section taken on line 6-6, Fig.

5, looking downwardly. Fig.' 7 is a cross section taken on line 7--7, Fig. 5, looking downwardly.

Referring tothe drawings: the numeral I designates the outer casing, which is provlded with thev air inlet 2, in which is. mounted the air inlet pipe 3, carry- 1ng the ydamper valve 4. The. outer casln 1s divided by the partition or horizonta plate 5, intothe small lower invertedly tapered chamber or compartment 6 and the lar e compartment or chamber 7 Mounte upon the upper face of the partition 5, and concentrically with the walls of the compartment 7, is a ring or rim 8, and provided centrally of this partition, and .eX- tending diametrically thereof, is the narrow substantially rectangular opening or slot 9, whereby communication 1s had between the lower and upper compartments, and whereby air is admitted into the upper compartment.

Upon the under side ofthe partition and guide strips l0, in which is slidably mounted the lataircontrolling'valve l1, which is adapted to close the entire slot, when desired, or when starting the engine.

Mounted in the walls of the outer casing and extending across the up er compart- .ment above the partition and a ove and parallel with the slot o'r opening 9, is the oil feed pipe 12, whose inlet end 13, is connected to the cock valve casing 14, which in turn is connected with the oil condensing or pressure relieving chamber 15, which in turn is fed with oil under pressure from the proper reservoir A, Fig. 4. Itv will thus be seen that the oil is delivered to the feed pipe 12, and when the parts are in the position as shown in the drawings, no oil is allowed to flow out of the pipe.

The cylindrical rod 16 has ,formed integral therewith the piston or cylindrical valve 17, which is slidably mounted inthe feed pipe 12, so that the valve 11, whose outer end a', is connected to the underside of the rod 16, will be operated simultaneously with the valve 17. The outer end of the rod '16 is reduced, for the operative connection of the lever B, Fig. 4:, thus enabling the two l valves to be operated as desired.

To allow oil to be atomized to produce the desired carbureted air, the lever B, is pulled upon, simultaneousl pulling the r-odlG and the iston or cylin r1cal valve 17 and also the at valve 11, but as the flat valve is purposely made longer than the piston valve, the piston valve passes beyond the opening 18, of the first; or riming nozzle tip or jet 19, and allowing oil to enter said nozzle and be atomized or sprayed through its centrall opening a and its two oppositely disposed openings b, the iat valve at this position of the piston Valve not having been moved far enough to open the end of the slot 9 and admit air. hese openings a and b, where heavy oil is used are larger than when light oil is used, as will be a parent. As the engine is started, the va ves' are moved outwardly, and as many of the remainin openings 20 and nozzles 21, are broug t into play, the slot 9, is opened and air admitted proportionatel f5 By positionin the slot, as I do directly below the oil fee pipe, and constructing the valves so that the slot is opened only directly below the desired nozzle or nozzles thatare brought in to use, it is evident that the current of air will strike the under side of the oil feed and be split, so that it will pass upwardly u on both sides of feed pipe, and as the nozz es deliver three s rays of oil, two directly int'o the sprays o air and one directly upwardly, it will be seen that the desired carbureted air is produced.

Removably fitting with theA u per com.

i partment and' having its lower e ge 22, fitting around the rim 8, is? the ta ered mixing dome or casing .23',1-whose out et 24 asses through the central pening 24', of t e removable top 25.ftheouter casing. This mixing casing is. provided with oppositely arranged slots 26, which allow the casing to fit over the oil feed pi e, and thereby confine the nozzles within t e same, while at the same time air is admitted only with the same. By fitting the mixing casing so as to cover the air inlet or slot 9 and the oil feed pipe and its atomizers, and providing the casing with the tapering opening 24, the tapered walls leading to said opening, receive the split streams of air, after the stream has been split by contact with the oil feed pipe, and bring said split streams toward each other and together, just prior to the emitting ofthe carbureted air through the opening 24 into the conducting pipe of the engine. By this means, I provide a thorough means of commingling the air and oil, and insure a thorough `commingled car- Vbureted air, prior to its entering the explosive chamber of the engine.

` To prevent any leakage of oil around 'the piston valve, I provide the stuffing-box 27, and also to prevent the pressure of oil from opening the valves, any controlling means B may be attached to the reduced end 28 of the valve.
